There’s lots of interest in going solar in Dripping Springs, Texas, a suburb of Austin. One question we commonly receive is, “How long will it take for the solar panels to pay for themselves?” It’s such a popular question, and it’s also pretty important, so we are happy to explain the answer below.

Solar Panel Costs & Payback In Dripping Springs

For most homeowners in Dripping Springs who finance a new solar roof, the average solar panel installation will pay for itself in 10 years. What this means is that over 10 years, the value of energy produced by a solar energy system should equal the cost to have the system installed. Payback period is also sometimes referred to as return on investment (ROI).

How did we get to the 10 year ROI figure for a home solar install in Dripping Springs? Our calculations are below.

A standard roof-mounted 13.34 kW solar energy system will produce approximately $2,500 dollars in energy each year. This assumes a $0.125/kWh value based on rates in the Pedernales Electric Coop service territory and average solar radiation levels based on a location in Austin, TX. The below results are taken from NREL PVWatts solar calculator:


Solar Costs & Rebates Explained

Using a cost of $3.07 per watt we have a gross cost of $41,001 for a 13.34 kW solar install (13,340 watts).

A 30% Federal tax credit is available for solar installs until the end of 2019. 30% of $41,001 equals $12,300, and we can deduct this from the gross cost since the tax credit is money you receive from the federal government on your income taxes. $41,001 – $12,300 = $28,701

Solar Rebates Available In Dripping Springs

Local installer Alba Energy is currently offering solar rebates and incentives for installations in Dripping Springs.
The maximum rebate available is $3,500 dollars which is based on a 10 kW system size or larger. Since this is money the solar company gives as a rebate after a solar energy system has been installed, you can also deduct it from your gross cost.

$41,001 – $12,300 – $3,500 = $25,201

So your net cost for a 13 kW solar panel installation in Dripping Springs, that is the cost after all rebates and incentives, is just $25,201 dollars.

And as we said before, the financial value of the energy produced by a 13.34 kW solar panel system in 1 year is equal to approximately $2,500 dollars.

$25,201 dollars net cost / $2,500 dollars worth of energy produced each year = 10.08 years, or 10 years until the solar panel installation pays for itself.
